fuel pump wiring woes

OK, a couple of disclaimers before I burden all of you with my trials. First, I am a real novice when it comes to auto electrical. Second, this is my first complete rewire of a car. Now the particulars. Car is a 70 Dodge Dart. Wiring kit is by EZ Wire. I have a MAD kit to move the battery to the trunk. I am also using MAD’s junction blocks for battery power under the hood. My problem: I am trying to wire up a Walbro fuel pump to a switch on the dash. The pump has a relay wired according to a member’s suggestions here on fabo. The EZ fuse block has dedicated wire for the fuel pump. Today I accidentally touched this wire to the battery junction block and the engine turned over. I have tested this fuel pump wire for voltage and am not reading anything. Yet there is obviously a completed circuit to the start circuit through this wire. I confess that I am out of my depth on this. EZ Wire really doesn’t include much in the way of instruction and zero info on troubleshooting. I have been trying to reach someone at EZ wire all afternoon but no luck. I should also mention that although I have 12+ to the relay the pump is not activating which is why I was messing around with the fuel pump wire in the first place. Sorry for the length of the post but I know more info is better when trying to solicit help from the more knowledgeable.
